NTK Direct Fit Oxygen Sensor 25213

NTK Direct Fit Oxygen Sensor 25213 is a specific-fit heated oxygen sensor for select Hyundai Santa Fe, Hyundai Santa Fe XL, and Kia Sorento applications. It is built for upstream right Bank 1 Sensor 1 placement, with OE-style fit, form, and function for emission control service.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement service
• 4-wire configuration with 16.2500 wiring harness length
• Threaded mounting type with 18.000 thread diameter
• OE-focused construction from NTK, the Sensor Specialist
• Part number 25213 for easy identification and ordering

Product Details

NTK 25213 is part of the Direct Fit Oxygen Sensor line, a product line focused on application-specific replacement sensors for import and domestic vehicles. NTK uses ceramic manufacturing expertise and controlled material processing to produce oxygen sensors with consistent electrical and sensing performance. This sensor is engineered for upstream right installation on 2010-2018 Hyundai Santa Fe, 2013-2019 Hyundai Santa Fe XL, and 2011-2018 Kia Sorento applications, making it a direct replacement for Bank 1 Sensor 1 service. This part cross-references DENSO Auto Parts 234-4463 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a failing upstream sensor
• Slow sensor response affecting fuel control
• Emission test failures tied to sensor degradation
• Driveability issues caused by inaccurate exhaust oxygen feedback

Installation Notes and Tips

Install in the upstream right Bank 1 Sensor 1 position only on the listed Hyundai Santa Fe, Hyundai Santa Fe XL, and Kia Sorento applications. Confirm connector routing, thread engagement, and harness length before installation. Because this is a threaded, heated, specific-fit sensor, matching the exact vehicle year, model, and position is important for proper operation.

Quality Assurance

NTK oxygen sensors are extensively tested during manufacturing to help ensure quality and reliability that meet or exceed OE specifications. As the world’s largest supplier and manufacturer of original equipment oxygen sensors, NTK supports OE application coverage with sensor technology developed for modern emission control systems.
